I tested it yesterday and it is much more rigid than Kimo's square. We get much faster hit on Kimo than on this combination. Once it went up to 12 numbers for 15 spins. You will win but you need a huge bankroll and iron nerves. When a few zeros come between you are ruined. I find the Kimo's square the easiest way to bet.
Yes, the crossings of numbers are only horizontal not also vertical like at Kingspin's and Kimo's squares.
Be careful with the middle number square because most of the time you have to cross 3 times the same number. The betting numbers grow fast to forget some to bet!

Hi,

Here are two sessions tests attached (casino Vittoriosa spins).
We get almost 10 to 12 numbers to bet in general on the 12 or 13 first spins.In the tests the win profit we get on 21 spin (almost 2/3 of the 36 spin cycle - 24).I think is good to stop somewhere between on 50 to 90 units target and quit.
According to the author we play each number for only 10 spins and stop (win or lose), so the numbers to bet will be less, also when 1 number hit that number is not more playable, remove from the next bet, but can appear some spins later as happen in one of the test (on number 28 I think) that was triggered for 2nd. time on other line.

Cheers,
